Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470570, here are decompositions:

7 + 31470563 = 31470570
13 + 31470557 = 31470570
23 + 31470547 = 31470570
101 + 31470469 = 31470570
127 + 31470443 = 31470570
191 + 31470379 = 31470570
211 + 31470359 = 31470570
233 + 31470337 = 31470570

Showing the first eight; more decompositions exist.
